💖 coresight_find_default_sink(9) 💖

okay bestie, welcome to the Kernel API Manual entry for coresight_find_default_sink — yes it's a whole function name, yes it's a mouthful, no we are not shortening it, it's iconic and we respect it 💅

✨ NAME ✨

coresight_find_default_sink — find a sink that's suitable for use as a default sink. that's it, that's the whole job 🎀

🦋 SYNOPSIS 🦋

struct coresight_device * coresight_find_default_sink (struct coresight_device *csdev );

like, look at her go. no notes. 🔥

🌸 ARGUMENTS 🌸

  • csdev — the starting source we're using to go find a connected sink. she's the main character, everything kicks off from her 🫶

👑 DESCRIPTION 👑

so here's the vibe: this function walks the connections graph looking for a suitable sink to enable for the supplied source. like she's literally strolling through the graph being picky on purpose 💅

how does she choose? she uses CoreSight device subtypes and distance from source to select the best sink. taste! discernment! we love a function with standards ✨

and if a sink is found? the default sink for this device gets set, and it'll be automatically used in future. no cap, she remembers, she's thoughtful like that 🎀

this whole thing gets used in cases where the CoreSight user (perf / sysfs) has not selected a sink. so it's the "bestie, I got you, I'll pick" fallback energy 🫶
